Cook's notes: *The instructor of the Peruvian Cooking class gave us some of this Aji Panca Sin Picante spice to take home. If you can't find it at the store, or don't want to try locating it, use smoked paprika or even chili powder. You'll still get a really nice stew.
** You can chop your veggies into whatever size you'd like. I made the chunks rather large to give some nice body to the stew. The only thing you want to keep in mind is that the potato pieces should be approximately the same size so that they cook evenly.
